Description Agostino Sarubbo gentoo-dev 2017-04-28 13:20:19 UTC
From ${URL} :

Quick Emulator(Qemu) built with the keyboard input event handlers support is
vulnerable to a host memory leakage issue. It could occur if a guest user was
to generate large keyboard events, faster than Qemu could process them.

A privileged user inside guest could use this flaw to exhaust host memory,
resulting in DoS.

Upstream patch:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
